XF 2.0 Some users (bots?) stuck in members online widget

[Northern Coder]

I have noticed for the last 2 days there are 3 unregistered users stuck in the 'members online' widget. When I click on each one I see they are viewing an unknown page for the last 2 days and I don't know how to remove them. Is this a bug in the forum or am I not doing the right thing.. banning, deleting the user.

I banned the ip's and it managed to make them go away.
